Suppose that in a population of shoppers, the proportion of people who had visited supermarket A last month is 0.18. Also that in the same population, the proportion of people who had visited supermarket B last month is 0.60. The proportion of shoppers who had visited both supermarket A and supermarket B last month is 0.12. What proportion of people in this population had visited supermarket A or supermarket B or both last month? (Give your answer to two decimal places.) Answer:

Researchers at a university designed and tested a​ speed-training program for junior varsity and varsity high school football players. Each in a sample of 38 high school athletes was timed in a​ 40-yard sprint prior to the start of the training program and timed again after completing the program. The decreases in times​ (measured in seconds) are listed in the accompanying table.​ [Note: A negative decrease implies that the​ athlete's time after completion of the program was higher than his time prior to​ training.] The goal of the research is to demonstrate that the training program is effective in improving​ 40-yard sprint times Find a 90​% confidence interval for the true mean decrease in sprint times for the population of all football players who participate in the speed-training program. (Round to three decimal places as​ needed.)
